' .fiThis vention relates to machines for pol- :i shihg"; liairepinsfi and other similar articles;

. and it consists in the novel construction and p of t e htheirfshafts and the carrier for the hair-pins combination of thedparts hereinafter fully de- In-the drawings, Figure 1 is a front viewof the" dishing-machine. Fig. 2 is a plan view polishing-machine. Fig.- 3 is an end View "0 the two polishing-wheels, showing in section. 1 Y I I A is a'eupport'mgirame which is of any approved' construction. 4 25.

,- Band C are two polishing wheels orbuffs whichfar'e formed of'any approved soft mate- "rial, such as cloth. These polishing-wheels are cylindrical inform and are journaled side side in 'the frame and provided withrneans for revolving them in opposite direc- I tions, as indicated by the arrows in Fig. 3.

. The whee C is mounted on a The wheel B is mounted on the shaft 1),

which is rovided with a driving-pulley b. si'paft c, 'whichis provided with a drivini-pulle -c. The said shafts are jour'naled in rovide'd with any approved means for adearings D, whichare 1usting them, so that the polishing-wheels are pressed together with any desired pressure. E represents hand-wheels for adjusting the position of the said bearings.

F is a carrier for the hair-pins. This carrier consists of an endless band. of flexible material; such as 'a leather beltflor a drivechain, and it is arranged to work in a horizontal plane. G is the driving-pulley for the said carrier, and 9 represents guide-pulleys over which the said carrier passes. f areal-l mounted on vertical shafts or spin- These pulleys dles carried by the said frame.

A wormwheel H is secured on the shaft h of thegdriving-pulley G, and H is a'worm which ears into the said worm-wheel. The

worm is securedton a shaft h, which is journaledin the frame A and provided with a r -Pu ley their axes.

. One portion 01 of the carrier is arranged in a jstraightline over the adjacent surfaces of the cylindrical polishing-wheels and parallel with The carrier is provided with a series of hooks J, and the hair-pins or other similar objects are suspended from these hooks and are traversed between the two polishing-wheel's. The hair-pins are polished by contact with the said wheels.

K is an adjustable knock-01f plate for the pins. This plate is secured to the frame in an inclined position and has its front end portion is curved crosswise of the carrierand ar-- ranged under it. The hair-pins strike this plate and are knocked off ,the supportinghooks. The knock-oif plate mabe raised or lowered on the frame to suit air-pins of different length.

What I claim is p 1. In a polishing-machine, the combination, with a pair of cylindrical polishingwheels'having their axes arranged .in a hori zontal plane, and means for revolving the said Wheels; of anendless carrier havmg a straight portion arranged edgewise over the adj acent. surfaces of the said wheels and sliding in a horizontal plane parallel with theaxes of the said wheels, and means for supporting and driving the said carrier.

-2. In a polishing-machine, the combination, with a pair of cylindrical polishingwheels having their axes arranged in a horizontal plane, and means 'for revolving. the. said wheels; of an endless carrier having a In a polishing-machine, the combinesupportin hooks secured to the said carrier; i

of means or supportin and driving the said carrier, and a knock-o plate for the articles having one end portion curved and arranged crosswise under the saidcarrier. 7
